Sentences with phrase «photons emitted per»

«Despite the early days in the raw materials manufacture, the quantum efficiency (photons emitted per electron injected) is already comparable to organic LEDs.»

Not exact matches

For example, from laboratory experiments we can determine the amount of amino acids produced per photon of ultraviolet radiation, and from our knowledge of stellar evolution we can calculate the amount of ultraviolet radiation emitted by the sun over the first billion years of the existence of the earth.

The photons emitted by such explosions, traveling at the speed of light, or about 300,000 kilometers per second, can still take billions of years to reach Earth, covering distances so vast it exceeds human comprehension.

A team led by Prof. Laszlo Veisz has developed a novel high - power laser capable of emitting bursts of infrared light — each consisting of only a few oscillation cycles — which contain 100 times as many photons per pulse as in conventional systems.

The details on a molecular level determine how likely a given transition is likely to occur — in other words, the fraction of photons of some frequency, polarization, and direction, that are absorbed over some path through an amount of material, and the number of photons of the same type which are emitted per unit time.

The answer that seems to fit that question is Miskolczi's GHG stabilisation model: total [H2O] falls to get constant IR optical depth corresponding to 1.87 average absorption events per photon emitted from the surface, a physical constant from the minimisation of free energy!
